I was listening to Bill Simmon's podcast today with Mark Stein, and he pointed out if they give Kemba the Supermax in Charlotte it would be crazy because they would be deep into paying the luxury tax with a team that has no realistic chance at a championship. He had a point.
He and Mark Stein also seem to think that after the chemistry-gone-bad-experiment with the Flat Earther / Drama Queen (my name for Irving, not their's) they are looking for high character guys like Kemba.
I would probably prefer Adams to inject a little toughness (especially mental) in addition to the high character he shares with Kemba to try to head off any corrupting influences that the Drama Queen had on the promising Celtic kids. However, maybe Kemba wouldn't be so bad as an alternative.
